When a keyway is damaged, cut a new, wider one. This key stock is stepped to match repaired keyways in shafts or gears. Cut it to length to create the machine key you need.

When installed, these keys fill oval keyways completely, reducing stress on the key and shaft. The rounded ends make it easy to slide gears, hubs, and other components into place. These are also known as feather keys.

Make a key that is the exact length you need. Slightly larger than the size listed, these oversized keys offer a tight fit in worn keyways.
